Crankcase is the common building block of engine.It refers generally to cylinder block bottom for installing the position of bent axle.It is bent
Axle box is generally divided into upper crankcase and lower crankcase.Upper crankcase and cylinder block cast solid, lower crankcase is used for storing lubrication
Oil, and upper crankcase is closed, therefore it is also called oil sump.
When engine works, the high pressure combustion mixture of combustion chamber and burnt gas can more or less pass through piston group
Gap between cylinder is leak in crankcase, causes gas blowby.The composition of gas blowby is unburned fuel vapor, vapor and waste gas
Deng this can dilute machine oil, reduce the performance of machine oil, accelerate the oxidation of machine oil, rotten.Condensation of moisture, can shape in machine oil
Into greasy filth, clogged oil line；Sour gas in waste gas is mixed into lubricating system, can cause the corrosion of engine part and accelerate mill
Damage；Gas blowby can also make the hypertonia of crankcase and destroy the sealing of crankcase, be lost in engine oil leakage.
To prevent crankcase pressure too high, extend machine oil useful life, reduce parts depreciation and corrosion, prevent engine from leaking
Oil, it is necessary to carry out crankcase ventilation.Existing crankcase ventilation typically adopt forced ventilation system, forced ventilation system it is main
Part is pressure-control valve and gs-oil separator；Operation principle is that the gas pressure in crankcase reaches pressure-control valve setting
During critical value, pressure control valves are opened, and gas is discharged, on a small quantity with the machine oil of gas discharge after gs-oil separator separation,
Return oil sump.But existing this ventilating system can not keep the gas in crankcase to be discharged completely, a small amount of gas
Residual still results in the abrasion of engine part.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of new type crank case ventage
System, it can keep the various gases scurried in crankcase to be completely discharged crankcase in time, keep the pure of machine oil, improve

Top middle portion, by ventilation unit ventilation left chamber and right vacuum cavity are isolated into；Aspirating hole is offered at the top of right vacuum cavity, bottom is in
Arcuate structure, bottom left offers the second ventilating opening；The bottom of lightweight pendulum valve is arranged to right vacuum cavity bottom with radian
Arcuate structure, is just covered on the second ventilating opening；The ventilation that first ventilating opening of crankcase passes through ventilation duct and ventilation unit
Left chamber is communicated, and the second ventilating opening of ventilation unit is communicated by body with gs-oil separator, the outlet of gs-oil separator respectively at
Petroleum pipeline and appendix connect, and the end of petroleum pipeline is connected to the bottom of crankcase；The aspirating hole and vacuum plant of ventilation unit
Connection.
Described lightweight pendulum valve is made up of lightweight foamed plastics.
Described vacuum plant is provided with timer, and vacuum plant timing working is pumped into the right vacuum cavity of ventilation unit very
Dummy status.
Operation principle of the present utility model is：Vacuum plant is evacuated the right vacuum cavity of ventilation unit, in crankcase
When having gas to leak into, because the ventilation left chamber of ventilation unit is communicated with crankcase, then the ventilation left chamber of ventilation unit is right with vacuum
Chamber produces pressure reduction, then lightweight is put valve and swung toward right vacuum cavity, then put the second ventilating opening and the ventilation left chamber that valve is sheltered from by lightweight
Communicate, gas enters gs-oil separator together with a small amount of lubricating oil from the second ventilating opening, Jing after gs-oil separator is separated, respectively from defeated
Oil pipe and appendix are exported, and waste gas is discharged, and lubricating oil enters crankcase.
After said structure, the beneficial effects of the utility model are：It can keep the various gas scurried in crankcase
Body is completely discharged in time crankcase, keeps the pure of machine oil, improves the service life of machine oil, reduces the mill of engine part
Damage, extend the use time of engine, it is reasonable in design, it is practical.
